Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Workings): Workings include at least 2 haulage adits, plus numerous crosscuts raises, shafts, and drifts on 15 levels.

Comment (Geology): The Stevens is a fissure vein that strikes north to NW and dips to the east; several parallel veins and a crosscutting vein are also present.

Comment (Location): Adit in Stevens Gulch on the west side of McClellan Mountain, in the SE/4 sec. 33, T 4 S, R 75 W, about 4 miles SW of Silver Plume.

Comment (Production): Incomplete production records show that between 1870 and 1911, the mine produced at least 4,800,000 lb of lead, more than 100,000 oz silver, and 250 oz gold. More recently, a company produced gold-bearing pyrite for samples of gold ore.

Comment (Reserve-Resource): Old reports that may be outdated describe stope fill and dump resources.
